I have two models in a belongsToMany relation. I have set up a backend form with a repeater widget that allows attaching a number of related models using values from the pivot table. I got it to save the data into the pivot table, but that data is never displayed on the form. Even the number of rows in the repeater widget are correct, but apparently the values never make it to the form fields (they are always null).

Here is my setup:

relation_config.yaml

knowledge:
    label: Knowledge
    pivot:
        form:
            fields:
                knowledge_id:
                    label: Field
                score:
                    label: Score

fields.yaml

fields:
    title:
        label: Academic program title

    knowledge:
        type: repeater
        form:
            fields:
                knowledge_id:
                    label: Field
                score:
                    label: Score

in Models\Program.php i have

public $belongsToMany = [
    'knowledge' => [
        'Blah\Mockup\Models\Knowledge',
        'table' => 'blah_knowledge_program',
        'primaryKey' => 'program_id',
        'foreignKey' => 'knowledge_id',
        'pivot' => ['score']
    ]
];

Am I doing something wrong?

@mihai8287 Did you get the answer? Because the same things happened to me.

You're treating your knowledge field with type repeater as a relation, which it is not.
